摘要
为提高上面层AC-13沥青混合料的路用性能,以S248线韶关市区过境段黄金村大桥至韶关钢铁厂公路改线工程二期(大学路—韶关钢铁厂)浈江段上面层为试验段,结合韶关市气候条件,通过配合比优化及路用性能验证,确定混合料最佳级配及最佳沥青用量,并对其高温稳定性和水稳定性进行评价。研究结果表明:通过对AC-13沥青混合料进行级配优化设计,沥青混合料具有良好的路用性能。
In order to improve the road performance of AC-13 asphalt mixture on the upper layer,the test section is taken as the upper layer of Zhenjiang(University Road-Shaoguan Iron and Steel Works)of the highway rerouting project phaseⅡfrom Huangjincun Bridge to Shaoguan Iron and Steel Works in Shaoguan urban area of S248 line.Combined with the weather conditions of Shaoguan,the optimal gradation and asphalt of the mixture are determined through the optimization of mix proportion and the verification of road performance.The high temperature stability and water stability were evaluated.The results show that the asphalt mixture has good road performance through the optimization design of gradation.
